Re: App Error 603

Error 507 means the device does not detect any operating system installed on the device.


See the link below for the download, and follow these simple installation instructions.

First locate your carrier and the OS file you wish to use.

1. Download the OS file to the PC then install it to the PC by running (double clicking) the file you downloaded.
2. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml."
3. Plug in BB and double click on "Loader.exe." It's located in the same place as the above vendor.xml file.
